In a post on Twitter, Mrs Clinton wrote: "JCC threats, cemetery desecration and online attacks are so troubling and they need to be stopped. Everyone must speak out, starting w/@POTUS."

The threats were made to the Jewish community centres through calls that were both pre-recorded and live, with suspects using voice-disguising technology, according to Israeli newspaper Haaretz.

Since the beginning of the year, there have been reports of threats to centres in New York, New Jersey, Ohio, Florida, Massachusetts, Maryland, Michigan, Minnesota, Delaware, Connecticut, Alabama, California, Maine, Tennessee, South Carolina, Missouri, Wisconsin, Texas and Kansas.

The Anti-Defamation League, a Jewish anti-bigotry organisation, said in a statement that it was "deeply disturbed" by the latest threats to the Jewish community.
